Dot Matrix

The dot matrix (also called frit band) is a ceramic-print pattern fired into the edge of vehicle glass. Its purposes are to protect the urethane adhesive that bonds the glass to the body from UV and to provide visual transition between the frit band and the clear glass.

For tint installation, the dot matrix creates a small air pocket between the film adhesive and the dotted area. Without specialist technique, a hazy or silvered effect appears along that edge.

Experienced installers like Infratint apply a heat treatment and use a dot-matrix-friendly adhesive technique to minimise this effect — never eliminating it completely but reducing it to barely visible.
